logged together with a four level sub information string giving a numerical value.logged together with a four level sub information string giving a numerical value.
** Any value Any value can be can be calculated to calculated to a voltage a voltage value from value from the following the following formula: value/formula: value/
1023 x 5.1023 x 5.
Example: Example: Value = 914, read volValue = 914, read voltage is 914/1023 x 5 = 4,48V. This meatage is 914/1023 x 5 = 4,48V. This means thatns that
values out of range are approximately below 409 or above 818.values out of range are approximately below 409 or above 818.
If the brake pedal is stamped hard, so the "Total brake switch" S4 is engaged, thereIf the brake pedal is stamped hard, so the "Total brake switch" S4 is engaged, there
is a possibility that error code E54 occurs in the display. The reason for this is thatis a possibility that error code E54 occurs in the display. The reason for this is that
the ATC cannot sample fast enough. This kind of E54 error is always loggedthe ATC cannot sample fast enough. This kind of E54 error is always logged
